Definitions

  • the invention relates generally to cylinder lock systems of the kind described in the international patent application No. PCT/SE87/00038 (WO87/04749), i.e. systems including a cylinder lock comprising:
  • the lock known from the above-mentioned international application has the special feature of a pivotable finger on each locking tumbler, so that the finger causes the respective tumbler to be specifically rotated when a properly shaped key is being inserted into the lock.
  • a very high number of code combinations and a good resistance against picking are obtained.
  • this feature makes the lock and the key blade relatively complicated and expensive.
  • the object of the present invention is to provide a cylinder lock and key system which is somewhat easier and less expensive to manufacture while retaining the most important advantages of the previously known system.
  • the inventive concept also includes a cylinder lock and key blade combination system with a master key, as defined in claim 7, and a locking tumbler for use with a cylinder lock, as defined in claim 8.
  • the key blade 1 shown in Fig. 1 has a longitudinal axis A of insertion and is insertable into the lock shown in Fig. 3.
  • the key blade is generally flat with substantially planar side surfaces 2 and 3.
  • the side surface 2 to the left in Fig. 2a has a minor step 4, and the side surface to the right in Fig. 2a has a longitudinal groove 5 with an upper side wall 6 inclined so as to face away from the blade 1 and a lower side wall 7 oriented substantially at right angle to the central plane P of the blade.
  • the lower edge surface 8 is slightly curved.
  • the longitudinal groove 5' has two mutually parallel side walls 6' and 7 oriented at right angle to the central plane P.
  • the lock 11 is of the rotary type and comprises a cylinder shell 12 and a key plug 13 rotationally mounted in the shell 12 to provide a shear line between the shell 12 and the plug 13 in parallel to the rotational axis thereof for receiving the key blade 1.
  • the lock 11 includes two rows 14,15 of locking tumblers or pins located in two mutually parallel planes.
  • a first row 14 of six locking pins is centrally located substantially in the central plane of the key slot 9 so as to cooperate with the upper edge portion 16 of the key blade 1, as described in the above-mentioned international application No. PCT/SE87/00038.
  • a second row 15 of five locking tumblers or pins 15a - 15e is laterally offset (to the right in Fig. 3).
  • each locking pin 15a - 15e is totally confined with the key plug 13 in a corresponding, cylindrical cavity or bore 17a - 17e, respectively (compare also Fig. 4).
  • the locking tumblers 15a - 15e in the second row are non-rotatably guided in the respective bores 17a - 17e and are each provided with a finger 18a - 18e, which projects transversally outwardly in a specific position into the key slot 9.
  • the locking tumblers 15a - 15e are only movable elevationally, and upon a specific elevational positioning of each such locking tumbler by means of a properly shaped key blade 1, a common fence member or side bar 19 will be allowed to engage into recesses 20a - 20e formed in the cylindrical surfaces of the body parts 21a - 21e of the tumblers and to be displaced transversally into its inward, seated position in the slot 22 of the key plug 13, thus clearing the shear line and releasing the lock.
  • the locking tumblers may engage directly with the cylinder shell (e.g. in the same manner as the locking tumblers of the first row 14).
  • Each locking tumbler 15a - 15e includes a substantially cylindrical body part 21a - 21e and a finger 18a - 18e with a relatively wide base portion 23a - 23e and a relatively narrow, substantially cylindrical free end portion 24a - 24e, as illustrated by the three different tumblers 15a,15b,15c shown in Fig. 6b, Fig. 6c and Figs. 6a,6d,6e, respectively.
  • the three different tumblers are all made from a similar tumbler blank 15' having a substantially cylindrical body part 21' and a likewise cylindrical or disc-like finger blank part 18', from which the material is cut out so as to form the desired finger end portion located centrally (24c, Fig.6a), to the left as seen in Fig. 6b (24a) or to the right as seen in Fig. 6c (24b). Compare also Fig. 6e.
  • the part-cylindrical base portion 23a, 23b, 23c, etc. of each finger is guided for elevational movement in a corresponding part-cylindrical bore 25a, 25b, 25c, etc. located adjacent and parallel to the respective bore 17a, 17b, 17c, etc. so as to be open transversally to the key slot 9 into which the respective finger end portion 24a, 24b, 24c, etc. extends for making contact with an inserted key blade.
  • the finger end portions 24a, 24b, 24c, etc. will be distributed in a specific, irregular pattern along the key slot 9, which pattern is generally different from the (normally uniform) longitudinal distribution of the finger body parts 21a, 21b, 21c, etc. in the longitudinal direction (in parallel to the key slot 9 and the axis A of insertion of the key blade).
  • the finger end portions 24a, 24b, 24c etc. make contact with the lower side wall 7 of the groove 5 provided in the side surface 3 of the key blade.
  • the side wall 7 there is formed an elongated, longitudinally extending wave-like code pattern surface, against which the finger end portions are urged downwards by means of compressive springs 26a - 26e (see Fig. 3) acting on the upper portion of the respective body part 21a, 21b, 21c, etc.
  • the opposite side wall 6' may be formed, e.g. by means of a cutter pin, with an identical configuration as the lower side wall code pattern surface 7, in which case the respective finger free end portion 24a, 24b, 24c, etc.
  • the one-sided or two-sided guiding surface (7 or 6',7, respectively) or the key groove 5,5' is rather easy to make, e.g. by means of a cutter pin in one step, since the guiding surface can preferably be perpendicular to the side surface 3 (and the groove bottom surface) of the key blade along the whole length thereof. Furthermore, the rest position of the respective finger end portion (in the fully inserted position of the key blade) does not have to be located in a concavity location (as was necessary in the lock and key system described in the above-mentioned international application) but may be situated at any well-defined, preferably substantially horizontal portion of the code pattern surface.
  • Figs. 7a, 7b, 7c there is illustrated how the recesses 20', 20'' and 20''' may be distributed elevationally in the body part 21 of the respective tumbler, wherein the recess 20' (Fig. 7a) can accomodate the side bar 19 in either one of two elevational positions (H2, H3), as can the recess 20''' (Fig. 7c, H1,H2), whereas the recess 20'' (Fig. 7b) requires the side bar to be in position H2.
  • the recess 20' Fig. 7a
  • Fig. 7c Fig. 7c, H1,H2
  • An essential feature of the present invention is that the free end portions of the locking tumbler fingers are located in specific, predetermined positions. In principle, this can be achieved with fingers each extending at a specific angle from the central axis of the tumbler body part. Another possible embodiment is illustrated in Figs.
  • the tumblers 15'a, 15'b and 15'c have fingers including a relatively wide base portion 23'a, 23'b, 23'c, which is guided in a corresponding recess adjacent to the bore housing the body part 21'a, 21'b, 21'c of the tumbler and thus prevents rotation of the tumbler, and a relatively narrow free end portion 24'a, 24'b, 24'c, each having a substantially triangular cross section with one rounded corner portion 27'a, 27'b, 27'c constituting a specifically located (to the left, centrally, or to the right as shown) bearing surface adapted to make contact with the code pattern of the key blade.
  • the predetermined, irregular longitudinal distribution pattern of the finger free end portions will also provide an advantageous possibility of establishing a master key system, as illustrated in Figs. 9a, 9b, 9c.
  • the relatively simple groove code patterns of the key blades 1' and 1'' are specifically configurated to correspond to one specific lock only (having the fingers 18'a - 18'e and 18''a - 18''e, respectively), whereas the more complex groove code pattern of the master key blade 1''' (Fig. 9c) includes all the critical code pattern portions of the key blades 1' and 1'' so as to match the predetermined finger positions of both locks. It will be understood that this principle can be applied in combination with differently located recesses in the body portions of the tumblers to provide a sophisticated master key system.
  • all of the finger end portions may be positioned alike, e.g. to the left, centrally, or to the right.
